Input and output streaming interface added for multiple channel implementations.
Capability added to specify hardware over sampling specification as a sample period.
Capability added to leverage over sampling factor to optimize resource utilization.
nd (new data) input port is now only placed on the block when Sample Period is
selected as the format.
Note:
This block supersedes the CIC Compiler 1.2 block. The RATE_WE signal no longer acts as a
reset to the core, the core will update to the new rate on the next input sample, for a single channel
implementation, or the next input to the first channel, for multiple channel implementations.
Refer to the topic CIC Compiler 1.3for more information.

New block now available in System Generator with the following features:
New option added to use the block as a Phase Generator or SIN/COS Lookup Table
only. This capability allows users to custom build a Direct Digital Synthesizer to fit
individual application needs.
